M10i Internet Router Hardware Guide

A V.35 connection requires an DB-25 to V.35 cable and connects to a V.35 data terminal equipment (DTE) 34-pin Winchester type male cable (one per port). Table 31 on page 204 describes the V.35 cable pinouts.

An X.21 connection requires an DB-25 to X.21 cable and connects to a X.21 DTE DB-15 male cable. Table 32 on page 205 describes the X.21 cable pinouts.
